BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a modular container, more particularly to a modular container having a plurality of wall plates.

2. Description of the Related Art

A container, such as a garbage container, a book or newspaper container, etc., has a tubular body that is sometimes made into a one-piece body, and at other times that is made by rolling a stainless steel plate to form a circular body, after which the ends thereof are joined together. Because the technique of making the one-piece container is rather difficult, the defective rate of the container during production is high. As to the method of rolling the metal plate and connecting the ends thereof, the appearance of the product is affected because the connection of the ends is exposed.

The applicant has developed a modular container that is capable of resolving the aforementioned drawbacks, its disclosed by the applicant in Taiwanese Publication No. 500112, referring to FIGS. 1 and 2, the modular container 1 includes a base seat 11, a tabular body 2, and a top frame 12. The tubular body 2 includes two wall plates 21 each having a substantially U-shaped cross section, and two fixing plates 22 interconnecting the wall places 21. Each of the wall plates 21 has two spaced-apart parallel plate sections 211, and an intermediate plate section 212 connected between the plate cent lone 211. Each plate section 211 has a vertically extending curled engaging edge 213. Each of the fixing plates 22 is made of plastic, and has two vertically extending grooves 221 formed respectively in two opposite sides thereof.

During assembly of the modular container 1, each fixing plate 22 interconnects two adjacent plate sections 211 of the wall plates 21 by sliding the corresponding fixing plate 22 along the curled engaging edges 213 of the two adjacent plate sections 211 through engagement between the curled engaging edges 213 and the grooves 221. Afterwards, the base seat 11 and the top frame 12 are fitted respectively to top and bottom ends of the assembled wall plates 21 and fixing plates 22.

Although the aforementioned modular container 1 can resolve the drawbacks associated in making the tubular body of the container, that is, the non-modular container described above, the curled engaging edges 213 of the plate sections 211 of the wall plates 21 are not only troublesome to process, but also must be formed with precision. If the curled engaging edges 213 are not formed with precision, the engagement between the curled engaging edges 213 and the respective grooves 221 may be either too tight, making it difficult to slide the curled engaging edges 213 downwardly along the grooves 221, or too loose, in which case connections between the wall plates 21 and the fixing plates 22 ere not strong. Since the modular container 1 requires high precision in the processing of its components, manufacture and assembly of the same are very inconvenient.

SUMMARY OF THE INVENTION

Therefore, the object of the present invention is to provide a modular container that can be easily and conveniently processed and assembled.

According to this invention, a modular container comprises a tubular body and a base seat. The tubular body includes a plurality of wall plates, and a plurality of pillars each interconnecting two adjacent ones of the wall plates. Each of the pillars has two wing plates projecting outwardly therefrom. Each of the wing plates has at least two vertically spaced-apart slots. Each of the wall plates has a plurality of spaced-apart side tabs engaged respectively to the slots in a corresponding one of the wing plates. The base seat is connected to and covers a bottom end of the tubular body.
